How to define Application wise Access Role(s)

We have several application in our environment, I need to restrict few applications to certain users, means a logged in user to the environment(Service Studio) must be able to access a particular application which he has been granted access to and must not view other applications on the environment.

Same condition must applicable once he logs in using OutSystems Now mobile App, he must able to access to application which he permission to access.

The link you shared suggests us for Role access at application level, I am looking for an option at Environment level Role access.

For Example:- I am trying to connect to an environment using OutSystems Now app URL option, so that i can see only those application for which i have permission not all applications available within Environment.
